License reservations (regardless of type) are an allocation of license tokens to a designated party. These reserved tokens are inaccessible for any other party once reserved, even if those tokens are not being used. These reservations are managed under the " Reservations " section of the " License Details " page for all licenses. Reserved tokens are used in the same manner as unreserved tokens, so the sole difference between the two is in who is able to access them.

Reserving Named-User

Licenses

Tools with named-user -locked licenses allow for tokens to be reserved for specific users. When a user matches the user pattern specified in the reservation, they will be able to access the reserved token. Named-User -locked licenses bind license tokens to users in the order in which they are requested until they are exhausted, after which new users will not be able to obtain license tokens. If a token is successfully acquired from a license without a reservation, then a reservation will automatically be created for the user that acquired the token. 

To reserve a named-user -locked license:

1. Open the License Server home page.
2. Choose Licenses > Tool Licenses and click the name of the tool for which you wish to reserve a named-user -locked license. The License Type column should indicate that the tool's license is User Locked Named User.

3. Under Reservations, click Add Reservation. The Add Reservation dialog opens.
   
4. Enter a regular expression to identify the user who should be able to claim a token. For more information about user patterns, see "Pattern Managing License Groups#Pattern Group Patterns" on the Managing License Groups page.
5. To add just this pattern, click Confirm. The dialog will close. If you want to add this pattern and keep the dialog open so you can add another one, click Confirm and Add Another.

1. Open the License Server home page.
2. Choose Licenses > Tool Licenses and click the name of the tool for which you wish to reserve a named-user -locked license. The License Type column should indicate that the tool's license is Floating.
   
   
3. Under Reservations, take note of the Tokens Reserved information, which shows you how many tokens are currently reserved against the total number provided for the license. You can add new reservations in two ways:
   • Pattern Reservations allow for reserving tokens for users who match a specified user/host pattern. Both the user and host pattern must match in order to access the reserved token. To add a pattern reservation:
     1. Click Pattern Reservations. The Add Pattern Reservations dialog opens.
        
     2. Enter a user pattern and a host pattern as regular expressions. Both are required. For more information about user and host patterns, see "Pattern Managing License Groups#Pattern Group Patterns" on the Managing License Groups page.
     3. Enter the number of tokens to reserve for users who match both the user pattern and host pattern.
     4. To add just this pattern, click Confirm. The dialog will close. If you want to add this pattern and keep the dialog open so you can add another one, click Confirm and Add Another.
   • Group Reservations allow for reserving tokens for Pattern groups and User Administration groups. Both Pattern groups and User Administration groups must be created before they can be used here. See the Managing License Groups page for more information. 
     1. Click Add Group Reservations. The Add Group Reservation dialog opens.
        
     2. Choose either Pattern or User Administration as the group type.
     3. Select the group you wish to use for this reservation from either the Pattern group or User Administration group dropdown, depending on which you chose as the Group type.
     4. Enter the number of tokens to reserve for users belonging to the selected group.
     5. To add just this group reservation, click Confirm. The dialog will close. If you want to add this group reservation and keep the dialog open so you can add another one, click Confirm and Add Another.

You can prevent specific users or user groups from reserving tokens, even if they match the user/host pattern or are part of the group used to reserve the floating license, by setting up a filter that specifically denies them access. A filter that denies access takes precedence over a competing filter that allows access. See Filtering License Access for details.
